v4.9.3 release candidate

[cpsievert]

TODO:

• Clean your package directory to remove any extraneous files, including ones that are git-ignored. (Warning, this will delete any unsaved buffers in RStudio! Also, be sure to close RStudio before taking this step!) git clean -xdf .
• Build your package. I (jcheng) personally do it from the Mac command line like this:
  PATH=$PATH:/Applications/RStudio.app/Contents/MacOS/pandoc R CMD build [pkgdir]
• Do a sanity check by installing/testing the built package.
• Run R CMD check --as-cran pkg_version.tar.gz both locally and on win-builder. You can also use https://r-hub.github.io/rhub/.
• Perform revdepcheck.
• Submit to CRAN via their online form.
• If there are R CMD check warnings that are unavoidable, make sure to explain them in the comments.
• When accepted, tag the RC branch with a v4.9.3 tag, and push the tag to origin
• Merge RC into master
• On master, change the package version to 4.9.3.9000
• Revert the changes in f47a771
